Commercial General Liability (CGL) Claim Denied: Occurrence, Exclusions, and Coverage Disputes

A commercial general liability (CGL) policy is designed to protect your business when third parties sue for bodily injury, property damage, personal injury, or advertising injury. When a claim is made against your business and your CGL carrier denies coverage, the stakes are high — you may be facing a lawsuit without insurance defense or indemnification. Understanding why CGL claims are denied and how to challenge those denials is critical for any business owner.

CGL Coverage Basics: What You Bought

The standard CGL policy (ISO CG 00 01 and its iterations) provides three coverage parts:

• Coverage A: Bodily injury and property damage liability
• Coverage B: Personal and advertising injury liability
• Coverage C: Medical payments

For Coverage A, the policy pays for bodily injury and property damage caused by an "occurrence" — defined as an accident, including continuous or repeated exposure to substantially the same general harmful conditions. For Coverage B, covered offenses include libel, slander, copyright infringement, and wrongful eviction.

Occurrence vs. Claims-Made: The Trigger Question

One of the most consequential CGL coverage questions is what triggers the policy:

Occurrence-based policies are triggered by the occurrence of the injury or damage, regardless of when the claim is made. If the injury happened during the policy period, the policy covers it — even if the claim is filed years later.

Claims-made policies (more common in professional liability but used in some CGL contexts) are triggered by when the claim is made, not when the injury occurred. Missing the reporting deadline or having a gap in coverage between renewal periods can create coverage gaps.

For occurrence-based policies, disputes arise over when the "occurrence" happened — particularly in cases involving long-tail injuries like latent disease, construction defects, or ongoing environmental contamination where injury developed over multiple policy periods.

Common CGL Denial Grounds

Expected or Intended Exclusion. Coverage A excludes bodily injury or property damage that is "expected or intended from the standpoint of the insured." If the carrier argues you knew or should have known your actions would cause harm — for example, a business that continued operating despite known safety hazards — it may invoke this exclusion. The standard is subjective: what did the insured actually expect? Negligent indifference is not the same as intent.

"Your Work" and "Your Product" Exclusions. The CGL excludes damage to "your work" — property damage to work you performed arising out of your work. This exclusion is central to construction defect disputes. If a contractor's defective work damages the work itself, the CGL typically does not cover the cost to repair the defective work. However, the CGL should still cover consequential property damage to other property caused by the defective work.

Contractual Liability Exclusion. The CGL limits coverage for liability assumed under contract, with an important exception for "insured contracts" (including most commercial indemnification agreements). If your business assumed a third party's liability in a contract and a claim arises from that assumed liability, coverage depends on whether the contract qualifies as an insured contract.

Employee/Worker Exclusions. Bodily injury to employees arising from employment is excluded from CGL coverage because workers' compensation is the exclusive remedy. Disputes arise over independent contractors, temporary workers, and "borrowed" employees.

Business Auto and Owned Property Exclusions. CGL excludes liability for vehicles (covered by commercial auto) and damage to property the insured owns, rents, or occupies. If the damaged property was yours, the CGL is not the right policy.

Pollution Exclusion. The standard "absolute pollution exclusion" in most modern CGL policies is written broadly and carriers apply it aggressively to chemical spills, emissions, contamination, and even some cases of indoor air quality or biological contamination. Whether a particular substance qualifies as a "pollutant" under the policy has been extensively litigated.

Late Notice. CGL policies require you to provide notice of an occurrence or claim promptly. While most states require the carrier to show actual prejudice from late notice before denying coverage, some states still allow late notice as a coverage defense. If you received a denial based on late notice, research your state's prejudice requirement.

Duty to Defend vs. Duty to Indemnify

The CGL's duty to defend is broader than its duty to indemnify. The carrier must defend any claim that is potentially covered by the policy — even if the underlying facts are unclear or the claim is ultimately unmeritorious. If the carrier is denying a defense, the standard it must meet is lower than the standard to deny indemnification.

A carrier that refuses to defend a potentially covered claim while reserving its right to dispute indemnification exposes itself to bad faith liability. If your carrier has flatly refused defense without a reservation of rights, that is a serious concern.

Reservation of Rights: What It Means

When a carrier defends you under a "reservation of rights," it is saying it will provide a defense while reserving the right to later deny indemnification coverage. This creates a conflict of interest — the carrier-appointed defense attorney may have an incentive to steer the case in a direction that benefits the carrier, not you. In this situation, you may have the right to independent counsel at the carrier's expense (the "Cumis counsel" right in California and similar doctrines in other states).
